Metal to Metal Seats
The metal-to-metal seat is composed by metal ring with special coating locked into metal seat. According to different environment, pressure, temperature and chemical composition
of the medium, different coating material is adopted such as Electroless Nickel, Chrome Carbide, Tungsten Carbide. With technology improved, the metal to metal seat provided by
GSVC is well done on zero leakage and surface roughness less than 0.2.
